Nanny Schedule

We currently have a live-in nanny from overseas. Her English is horrible and I don't get along well with her, so we're looking into getting someone new. Having her has been nice though. I'm up with the babies in the night, so I get my toddler up, bring her to the nanny, then nap. I kind of have the mornings to myself. But, another issue, is the nanny really does everything. I'm a SAHM, so I would like to do stuff with the kids, too, but totally still need a break, as I'm sure you all understand. It's a balance; I still need to be mom, but need the extra pair of hands.

Anyways, I'm trying to figure out what to tell the new nanny about my scheduling needs (this'll be a nanny share; she watches a 2 & 4 year old and will add my kids to the mix). If you stayed at home, but still had help, what kind of help was it? Every day? All day? Only a few hours? The great thing about a nanny is I can spend solo time with DD1 or with DD2 and DS, or whatever combo! Otherwise I don't see how that's possible.

I guess I'm wondering what some of your nanny/childcare schedules looked like. Thanks!
